Although I have described a specific means of mounting the protecting member upon the caster, I wish it to be clearly unany suitable means may be employed to rotatably, mount the member upon a caster.

In Fig, 4 I

have shown a slightly modified form in which.

the flange 11 lnstead o'fi depending from the peripheral disk. is bent upwardly to form a protector not only for the caster but for the leg 1, it being noted that the diskis of a greater diameter than that of the leg.
